Yes, saxifrage is rated fire resistant, with three regional plant guides recommending it.
King County’s forestry program lists Saxifraga spp. among its fire-resistant perennials for western Washington. Catalonia’s provincial government and fire service also rate it “recommended” under a five-level garden-suitability system. Their method weighs fire-resistance literature and firefighter experience alongside fuel structure, maintenance, origin, and invasiveness. New Mexico’s Forestry Division includes saxifrage among FireWise flowers and ground covers, but its elevation guidance matters: it recommends the plant from 6,000 feet through 9,000 feet and above, marks 5,000 feet unknown or doubtful, and does not recommend 4,000 feet. That listing also assigns medium-to-high water need.
The guides reach the same practical conclusion through different methods. King County uses presence on an expert-curated fire-resistant list; Catalonia makes a broader qualitative judgment about garden suitability around wildfire; New Mexico pairs its recommendation with growing conditions, including sun or partial shade and a mature height of one-half to one foot. None of these findings means the perennial cannot burn. “Fire resistant” is a landscape recommendation, not a promise of noncombustibility.
For a homeowner choosing saxifrage, the case is reassuring but regional. It has affirmative support from agencies in very different places, while New Mexico’s elevation limits show why local conditions still belong in the decision. Saxifrage is reasonably treated as a fire-resistant planting where the relevant guidance recommends it and its stated growing conditions fit the site.

Fire evidence
Fire-resistant — location does not change the cited classification.
King County's current wildfire page links this list for the Puget Sound Basin. FireApproved publishes 82 exact source owners as basin context, not statewide Washington guidance or a site-specific recommendation.
New Mexico Forestry Division publishes this as its FireWise Plant List for New Mexico. FireApproved accounts for all 140 printed rows and publishes 95 exact same-rank owners already represented in the directory; 29 exact taxa without an existing record, 14 unresolved spellings or higher-rank matches, one compound taxon cell, and one species row whose only apparent owner has an infraspecific printed identity remain held. Every published row retains the source's Y, N, ?, or blank elevation cells. Publication scope does not erase those elevation limits or establish suitability for every New Mexico site.

How to read this page
The status above is computed from the cited rows below: independent recommendations can support a fire-resistant result, an avoid row can produce keep-away, and disagreement stays visible as conflict. Placement notes preserve each source’s own scheme rather than translating unlike rules into one scale. This is evidence about a plant, not permission to plant it in every part of the defensible space; Zone 0 remains noncombustible.
Where its sources say to plant it
Placement rules below use each source's own distances or named zones, tied to its rating.
They are not interchangeable with the directory's current Zone 0 guidance.

The evidence
Grouped by what each source concluded. Primary evidence rated the plant itself
(a lab, field program, or original curation); corroboration compiled or
republished another source's rating and resolves to its root lineage.
Saxifraga spp. is rated “RECOMENDADA” by the guide's qualitative IUF garden-suitability method. The method assumes species-specific care and integrates fire evidence with fuel structure, maintenance, origin, invasiveness, and expert fire-service experience.
